Alison is right for that part. To find the refill for the pencil it’s in the cabinet on the left where the toilet is. Scribble on the pad of paper until you see the code: 1425, (red; yellow; blue; purple) for the color door downstairs. It’s asking for something else but, I don’t know what it is. Does anyone know? That information would be very useful.

Jajajaja, it’s a pencil actually, those you put one of those graphite refill
Where are you? First, you make the cat a coffee with the mug in the kitchen, the coffee in the cupboard next to the door, the milk behind the living room curtain, the hot water that you get by putting the kettle (that’s upstairs, in the cupboard) under the sink and open the tap and then put it on the stove to heat it up. Also, there’s some sugar in some of the cupboards in the kitchen and a spoon in the second machine in the kitchen.
After that, click on the cat that wants coffee and put all the things on the table. It will give you a key for the bathroom/washing room where you have to smash the bug with the paper you get under the table. It’s a bit hard but then the cat gives you a card for the door upstairs.
Also, you have to get from the closed thingy (like a green tube) a paper with a Grey/silver key on the back for the blue box. To open the green tube you need the cutter, which is in one of the drawers in the kitchen. Inside the blue box there is some glue, which you have to use for the broken cupboard next to the stairs. Inside you have an umbrella to help you get the coin behind those boxes under the stairs. Upstairs, the door is opened with the pink card and the code, which is the one in the paper with the cat which you have to scratch with the coin. Then, just make the puzzle with all the puzzle pieces and paint it with the brush from the bathroom (please go to the kitchen and wet it).
Then, I’m stuck…
